New Favorite Coffee
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1), Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
Let me start out by saying I am a coffee fiend. I drink it all hours of the night and day and I've tried just about every brand you can think of. I took a chance ordering this and I'm so glad I did! Reading the other reviews helped me so I hope this helps someone else, too.
No one is paying me for my opinion, I'm not getting a single thing for writing this except the satisfaction of reporting on a quality product.
Not only is it a good price for how much you get, (09/25- $22 for 35.2 oz) but this is some of the smoothest coffee I've ever tasted. The beans are so shiny and just pretty. They're not all dried out and dull and dessicated looking like some coffees... The beans smell so good in the bag and even better once I've ground them. They grind up very quickly and easily too. There's no bitter aftertaste. Just pure, delightful, delicious coffee.
I got the 5/10 espresso, and it's perfect for me. it's just strong enough. I like medium-strong roasts, so if you prefer darker or lighter roasts they have plenty of other options.
I use both a drip coffee pot and a French press and this works beautifully in both. The crema in the French press is gorgeous.
It's so far above other brands- even Seattle's best and eight o clock and Cameron's, which I thought I really liked... They don't hold a candle to this.
I can't wait to try the other flavors.

Good Beans for Home Espresso
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
I’ve been using these beans daily for about two weeks in my espresso machine, and they’ve been really consistent. The flavor is smooth and easy to drink, with a mild nutty note and low acidity. It’s not overly bitter, which I personally like for everyday coffee.
One thing I noticed — you do need to dial in the grind a bit to get the best crema, but once you do, it comes out pretty nice.
On the downside, the aroma and intensity are a little on the lighter side. If you’re into strong, bold espresso, this might not hit that mark.
Overall, this is a great everyday option — especially if you want something smooth and reliable without too much bitterness. Good value for the size too.

Economical, great taste and refreshing.
Flavor Name: Kiwi Strawberry, Size: 16.9 Fl Oz (Pack of 12)
very refreshing and nice flavor. I will definitely buy again. Great bottle size for hiking. Ingredients are blended well and the calorie count is low. Buying a multi-pack is also economical.

Crisp, Refreshing, and a Family Favorite
Flavor Name: Kiwi Strawberry, Size: 16.9 Fl Oz (Pack of 12)
Propel Kiwi Strawberry is one of our favorites. It’s crisp, refreshing, and has just the right amount of flavor without being overpowering. The kiwi strawberry taste is especially enjoyable and makes it easy to drink throughout the day.
We also like that it’s zero calorie and includes electrolytes and vitamins, making it a great option for staying hydrated during workouts or busy days.
Overall, a consistently refreshing drink that we always keep stocked in the house.

Excellent product. But I thought they were expensive.
Flavor Name: Kiwi Strawberry, Size: 16.9 Fl Oz (Pack of 12)
This is a great product, great ingredients, excellent taste, sugar-free. My friend a actually came over and I think he drink most of them or took them home to his wife. Didn't last long and I thought they were pricey.
